1426-1430 Irving St, San Francisco, CA 94122

The two-story multi-family residential building at 1426-1430 Irving Street, owned by Kafong Holdings LLC, was constructed in 1946 and contains three units. The property has undergone several significant improvements in recent years, with the most notable being the conversion of the adjacent ground floor space (1428 Irving) into an animal hospital in 2021, which required substantial construction work valued at over $238,000.

This project included new partitions, ceilings, lighting, and associated mechanical systems, along with the installation of a solar PV system in 2024 with 42 modules totaling 18.060 kWdc. The building has received consistent maintenance attention, including a recent split unit installation with duct work in 2023, reroofing projects in 2023 and 2011, and various plumbing upgrades such as a complete copper repipe in 2009 and multiple fire safety improvements in 2021-2022. The property has experienced some recurring issues with graffiti, particularly during and following the COVID-19 pandemic, with multiple incidents documented between 2020 and 2025, though recent cases have been marked as "Not Offensive" and are still open.

The building has also undergone several infrastructure improvements including a new backflow system, fire sprinkler installations, and various HVAC upgrades including the installation of a gas furnace and condenser in 2021. A noteworthy environmental health inspection was conducted in December 2024, and there was one tree-related incident in 2021 that was resolved by stump removal. The property's recent history suggests active management with regular maintenance and upgrading of facilities, particularly focusing on fire safety systems, HVAC improvements, and the integration of sustainable technologies like solar power.
